Femme-MACHINE- SPECIFICATION forming part of `Letters Patent No. 742,299, dated October 27, 1903.

Application filed May 8,1901.` Serial No. 59,291. (No model.) l

To all whom it may concern:

Be it known that LWELLINeToN DowNING, a citizen of the United States, residing atErie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Folding-Machines; andI do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to folding-machines; and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and pointed outin the claims.

The invention is illustrated in the accompanying drawings, as follows:

Figure 1 shows a plan view of the machine. Fig. 2 shows a side elevation from the bottom of Fig. 1. Fig. 3 shows a side elevation from the right of Fig. l.

A marks the frame of the machine; B, the feed-board; C, the drop-roll; D D, the firstfold rolls;` D', the starter for the first-fold roll; E E, the second-fold rolls; E', the starter for the second-fold rolls; F F, the third-fold rolls, and F the starter for the third fold rolls. The tapes c carry the paper from the drop-roll C over the first-fold rolls. The tapes d carry the paper from the'first-fold roll over the second-fold roll and the tapes e from the second-fold rolls over the third-fold rolls. Arranged on the drop-roll C is the perforator C', `which is in line with the rst-fold roll. At each side of the perforator C is a perforator C2. These are at equal distances from the perforator C', so that they are brought into register by the first fold. The mechanism is arranged to bring the perforations made by the perforators C2 C2 over the second-fold line, and the second fold is made along these lines of perforations. The third fold is made at an angle to the first and second folds, ordinarily at a right angle. This arrangement of perforations permits the folding of two parallel folds and then a fold at an angle to these parallel folds without buckling.

I am aware that perforations have been used for preventing buckling; but I am not aware that perforations have been arranged so as `to make lines of perforations at proper distance from the first fold to form a foldline Vfor the second fold, and I am not aware that three lines of perforations have been used where two parallel folds are made with a third fold at an angle to these folds. Any desirable means of operating mechanism may be employed and any desirable means of droproll mechanism may lbe used. chine shown it is as follows: A drive-pulley G is arranged on the drive-shaft G. A gear g on the shaft meshes the gear H on the shaft H. The gear D2 on the shaft H' meshes the gear D3 on the roll D, and a gear D4operates the companion roll from the gear DB. EX- tending from one of the rollsD is ashaft carrying the gear D5. This gear meshes an intermediate gear E2. The intermediate gear E2 meshes the gear E3, which is carried with the roll E. The companion roll E is driven from the roll E, connected with the gear E3, in the ordinary manner. Arranged on the shaft H is a gear H2, vand'meshing this gear is a gear F2. The gear F2 is fixed on the shaftF3,which is connected with the roll F. The second roll F is driven by the first roll in the usual manner.

The drop-roll C is carried by an arm C3, which is arranged on a rock-shaft C4.. A gear H8 is fixed on the'shaft H', and meshing this gear is a gear I. The gear I is fixed on the shaft I'. The cam C5 actuates the lever C6. A. link C7 connects the lever C6 with an arm C8. The arm C8 is fixed on the rock-shaft C4. The drop-roll is operated by this mechanism. Arranged on the shaft G is a gear G2, and meshing this gear is an intermediate gear C9. The gear C9 meshes the gear C10 on the feedroll C12. A gear C11 is arranged to operate the drop-roll from the feed-roll. The stop C13 is carried by the rod C14. The rear end of the stop is engaged by the arm C15 on the rockshaft C4. It will readily be seen that with the downward movement of the drop-roll the stop G13 will be raised. A camrlis arranged on the shaft I. An arm D,operating on this cam, actuates the starter D', and thecam t" on the shaft I' operates the starter E through an arm E4. A cam F4 on the shaft F3 operates the starter F' through an arm F5. A stop'c is arranged to position the'paper over the first-fold roll and a stop d is arranged to position the Iny thema- IOO paper over lhe second-fold roll, so as to bring the perfor-ations formed by the perforations C2 C2 over the second-fold line.

What I claim as new is- I. In afolding-machine, the combination of the rolls, D D and rolls, E E, arranged in parallel relation; the dr0p-rol1, C; the perforators, C2, C and C2, on said drop-roll in therelation described; means for conveying the paper from the drop-roll over the first-fold roll and from the first-fold roll to the second-fold roll; a third-fold roll arranged at right angle to the second-fold roll; and means for conveying the paper from the seeondfold roll to i5 the third-fold roll.

2. In afolding-maehine, the combination of WELLINGTON DOWNING.
